Embodiment Construction

[0037] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] combine figure 1 As shown, when adopting the method for connecting the ring-hanging rail beam and the corbel of the present invention, when the ring-hanging rail beam and the corbel are fixedly connected, the following steps are specifically included:

[0039] Step S1, after completing the high-altitude fixed installation of the corbel, directly hoist the ring-hanging rail beam to the corbel, and perform assembly and position adjustment of the ring-hanging rail beam on the corbel. Among them, by adjusting the position of the assembled ring-hanging rail beam, all the connecting holes on the ring-hanging rail beam correspond to the corbels.

[0040] In addition, the corbel is a metal component and is fixedly connected to the containment steel-lined cylinder by welding. At the same time, the backing plate of the jack base for installi...

Abstract

The invention belongs to the technical field of nuclear power construction and particularly relates to a construction method for connecting ring crane bearing rail beams and brackets. The problems that in the prior art, when the ring crane bearing rail beams and the brackets are connected, the construction efficiency is low, and connecting accuracy is low are solved. The connecting method of the ring crane bearing rail beams and the brackets comprises the steps that S1, after the brackets are fixedly mounted in the high place, the ring crane bearing rail beams are directly hoisted to the brackets, and the ring crane bearing rail beams are assembled and adjusted in position on the brackets; S2, according to the positions of connecting holes in the ring crane bearing rail beams, corresponding bolt holes are directly drilled in the brackets in a matched mode; and S3, after the bolt holes are drilled and machined in the brackets in the matched mode, the ring crane bearing rail beams and the brackets are connected for fixing directly through bolts. The ring crane bearing rail beams and the brackets are connected through the method, the construction period can be shortened, the construction efficiency is improved, and the connecting accuracy can be improved.

Description

technical field [0001] The invention belongs to the technical field of nuclear power construction, and in particular relates to a construction method for connecting a ring-hanging rail bearing beam and a corbel. Background technique [0002] The reactor building of a nuclear power plant is generally a cylindrical building, and 36 supporting corbels are evenly arranged on the steel lining inside the cylindrical building, and a ring-shaped ring crane supporting rail beam for the rotating operation of the ring crane is laid on the corbel. Wherein, a connection hole is provided on the ring suspension rail beam, and a bolt hole is provided on the corbel, so that the two are connected and fixed by bolts. [0003] At present, the steps for connecting and fixing the ring-hanging rail beam and the corbel are as follows: firstly, the ring-hanging rail beam is assembled on the ground, and the positions of all the connection holes are measured for the assembled ring-hanging rail beam. ...
